The Kaedehara clan was long considered extint since people thought Kazuha wasnt interested in keeping the blood line going or even teach the Isshin art to others. However that soon changes when he moves back to Inazuma and marries you– his spouse.
Of course you first showed interest in learning the Isshin art but crafting swords –or weapons in general– was far more difficult than you originally thought. You didnt do well and that was okay with Kazuha; its not like he married you to keep the clan or traditions going. However, people soon got word about yout inability to learn the craftship of weapon making and soon started to talk behind your back.
Kazuha spotted a few people badmouthing you as he was peacefully taking a stroll around the neighborhood– unaware that you were watching him from the distance with a smile through the window. Wanting to greet your husband, you walk outside of the house, now hearing what he and one of the neighbors are talking about.
"Oh, by the way. If you ever speak disrespectfully about my spouse again I will kill you." He says with a innocent smile and a chuckle before grabbing the other person's collar, his gaze suddenly turning really intimidating. "Sorry, that sounded like a joke. I will actually kill you"
Kaedehara smiles once again before letting the neighbor go, turning now around in order to greet you.
"Hello love, I didnt see you there." Kazuha says with a puppy-like behaviour. He sure switched fast.
